Patent number: 9441672Abstract: A method for producing a holder in which sagging is suppressed in a bent part to be formed into a flange portion, without using bulge forming and a split mold that restrains the inside of a working target article; and a holder. An upper punch presses and bends one end portion of a working target article inward, whereby a flange portion is formed in the one end portion. A smaller-diameter portion of the working target article is restrained from the inside and outside by a lower punch and split mold portions. Then, a peripheral surface portion of a convex portion of the upper punch receives the end portion of the working target article and applies an outward pressure to the end portion. A bent part is pushed toward a larger-diameter portion restraining part of a split die, so that sagging is prevented from occurring in the bent part.Type: GrantFiled: March 6, 2013Date of Patent: September 13, 2016Assignee: NTN CORPORATIONInventors: Yoshiya Mano, Hiroshi Nakahashi, Kouhei Kondou, Hajime Kawamura, Shingo Kinpara, Yasunori Yamamoto

Patent number: 9237627Abstract: Short circuit failures and open circuit failures of light-emitting elements used for the backlight in an LCD panel can be reliably and easily detected. The voltage at the node between each series-connected light-emitting element array and a drive circuit is detected as a monitored voltage. A maximum detector detects the highest and a minimum detector detects the lowest of these monitored voltages. Short circuit or open circuit failure of a light-emitting element is detected by comparing the voltage difference between the maximum detector output and the minimum detector output with a specific reference voltage.Type: GrantFiled: September 25, 2014Date of Patent: January 12, 2016Assignee: PANASONIC CORPORATIONInventors: Go Takata, Shinichiro Kataoka, Yasunori Yamamoto, Tsukasa Kawahara, Ryuji Ueda, Daisuke Itou
